Patented Sept. 10, 1935 13 Claims.

My invention relates generally to calendars and particularly concerns along term calendar. Y The calendar upon which this invention is based ispreferably comprised of a backing and a card which are operativelyrelated to each other in a manner whereby the chart for any month forsubstantially any year may be easily and quickly determined. Morespecifically it is desired to provide a calendar comprising thecombination of a backing and a card which are bodily and relativelymovable.

Another important object of my invention is to provide a calendar of thekind above referred to in which a novel arrangement of indicia isprovided adjacent the opposite sides of the backing and the sides of thecard in a manner whereby the above result may be obtained.

A further object is to provide a calendar in which the thirty andthirty-one day months are correctly given, including information bywhich the correct number of days for the mo-nth of February can bedetermined whether a leap year or not.

It is also an object of my invention to provide a calendar in which theindicia provided thereon is arranged in a manner whereby it issubstantially impossible to read the calendar incorrectly.

A further object of my invention is to provide means which will adviseone as to the limits to which the card is adapted to be moved orotherwise shifted, in order to prevent accidental displacement of thecard with respect to its relation to the backing member.

A still further object of my invention is to provide a calendar which isvery simple in design and construction and which may be easily andquickly operated; also one which is very durable and inexpensive tomanufacture.

Many other objects of my invention will appear after considering thedescription hereinafter set forth in connection with the drawinghereunto annexed, in which several figures of the calendar are clearlyshown.

With reference to the drawing, Fig. 1 is a front plan view in elevationof a preferred form of the calendar showing the backing and card membersassembled;

Fig. 2 is a section taken on line 2 2 of Fig. 1 showing more in detail,the manner in which the card is operatively associated with the backing.member;

Fig. 3 is a rear View in elevation of the calendar shown in Fig. l,disclosing the novel arrangement of indicia provided on the back of thebacking and the back of the card; and

Fig. 4 is a view showing the card detached and the novel arrangement ofindicia provided on the face side thereof.

Considering the principles of design and construction involved in myinvention of which one embodiment thereof is shown in the drawing,numeral I indicates a backing member which, obviously, may be of anydesired shape or of any suitable material, however, in the present caseis rectangular in shape and made of cardboard. The card which isoperatively related to the backing is identified by numeral 2, and thetwo are made bodily and relatively movable by slitting or scoring thebacking in a plurality of places in order to provide a plurality ofbands 3, 4 and 5, between which and the backing the card extends. Thusthe card 2 is held in guiding relationship to the backing member.Obviously, bands other than 3, f3 and 5 may be provided, or thearrangement changed.

The backing, as clearly shown in Fig. 1, is provided with a plurality ofsight openings such as 6, 1, 8 and 9, the material from which theopenings 6 are made being entirely removed. The sight openings arepreferably separated by integral strips such as I0. A row or column ofyears including 1934, 1935 and 1933 are provided on the face of thebacking, and to the right of this row of days of the Week are arrangedon the strips in a row in spaced relation to each other, and to the rowof years at the left. Obviously the days of the week may be arrangedotherwise.

As shown in Fig. 3, there is provided adjacent the back of the backingI, a column of years II and a column I2 of leap years, preferablyarranged in spaced parallel relation. The column of years I I is dividedtransversely into a plurality of banks of years such as I3, which rowsare separated by spaces I4. The bank I5,.as shown, includesV the years1900, 1906, 1917, etc. The leap year column I2 is provided with banks ofyears such as I6 arranged transversely of the column and separated byspaces I'I.

Concerning the indicia arranged adjacent the face of the card member 2,and referring particularly to Fig. 4, the months of the year arearranged in the column designated I8 and duplicated, except the monthsof April and July which appear but once, and a row of numerals I9 is inline or lie opposite in spaced relation to each month; that the days ofthe month from I to 3l are consecutively duplicated with the exception Jthe years in bank 2. year column I2 the chart is set for the months ofthat the numerals are formed into six columns, the numerals in eachcolumn being irregularly positioned. To illustrate, the month of March,including numerals 4, II, I8, and 25 form a row, and this appliesthroughout, with the exception that a number of the rows of numeralssuch as 29 are not accompanied by the name of any month.

With reference to the indicia arranged adjacent the back of the card 2,it will be clear from Fig. 3 that two columns of months 2I and 22 arearranged 1n spaced parallel relation to each other. The months in column2i are arranged in transverse rows or banks such as 23, and the monthsin column 22 are also in rows as indicated at 24.'

It is to be noted that the months of February and November appeartogether in one row in column 2l, and that said months each appeartwice; the same applies to the months of January and October. The columnof months 2I, and column I8 are similar in respect to the number oftimes each month of the year appears in each column. The column 22 issubstantially the same as column 2I, except in the latter column, themonth of January appears but once; that January and July are combined inone row or bankV instead of January being combined with the month ofOctober, as shown in column 2 I; also the months of October and Novemberappear in separate rows. The year columns II and I2, are each providedwith a plurality of transverse spaced lines such as 25, and lines suchas 26 are provided in the columns 2I and 22 provided adjacent the backof the card member. The lines 25 and 26 are adapted to provide guides ormeans by which to determine the proper position of the months of theyear, and the days of the months in the various sight openings, such as6 to 9, inclusive, provided in the backing member.

Considering the operation of the calendar, and assuming the card andbacking are in the position shown in Fig. 1, it is evident that thechart for the month of July in 1934, the first and thirty- A. rstthereof appear on a Sunday and Tuesday, respectively, and that the chartis applicable for the month of December, 1935, and the months of Januaryand October 1933. Referring now to the back of the calendar, as shown inFig. 3, it will i be clear that the chart for July is also applicable'for the bank of years I5 in the year column II,

and for those months which appear in line with a bank of years, as forexample, the chart is good for the month of May in the year 1910, andfor By referring to the leap January and July 1928 in bank 28, for March1908 and 1936, in bank 2,9, and so on down. The month of February in thecolumn 2| provided on the card will have 28 days, and in the leap yearcolumn 22 February will have 29 days in the month; such informationbeing preferably indicated on the card as shown. To further illustratethe operation of the device, assume that the card 2 is lowered so thatthe month of September adjacent the back thereof is arranged opposite orin alignment with the bank of years I5, and it will be noted, whenreferring to the face of the calendar that the chart ,for the month ofSeptember will register 30 days, the first falling on a Sat- V beevident that the month of February provided in the column 22 will be inline with the bank 29 of leap years 1908 and 1936, and thus there willbe 29 days in the month of February for these years. It is to beunderstood, that the correct number of days in any month of the year,except February, may be made toy register in the sight open- 5 ingstherefor when the month desired is moved opposite the desired year. Insuch case the number of days in any month in any year may be easily andquickly obtained, however, the name of the month desired will not alwaysappear in the 10 sight openings provided for same, as for example,assume the card has been moved so the month of December in the column 2I is opposite the bank of years I3 in which the years 1909, 1915, etc.appear and it will be evident when referring to the face 15 of thecalendar that the chart discloses the months of August, May, and Marchfor the years 1934, 1935, and 1933, respectively, when in fact the chartis applicable for the month of December, in year 1909, though said monthdoes not appear 20 in any sight opening. Y

It is to be particularly noted that the arrangement of the months whichincludes the columns I8, 2I and 22, are such that it is substantiallyimpossible to operate and read the calendar in- 25 correctly, especiallyso with reference to the appearance vof any of the months in the columnI3 in the sight openings such as '1, 8 and 9. Also, it is to be notedthat the particular indicia arranged in the various columns willobviously have 30 to be rearranged as time passes.

The corners of one end of the card member 2 are beveled as indicated at30, to assist in placing the card in operative relation to the backing.y

As above stated, means are provided by which 35 to determined the properlimits to which the card is adapted to be moved. This is accomplished byplacing the word stop, as indicated at 3l, on the face of the card, andwhich will appear in the v sight opening 'I when the card is moved to acer- 40 t-ain position in one direction, and a line 32 provided adjacentthe back of the backing indicates the distance towhich the card isadapted to be moved in the other direction, thus the upper end n of thecard 2 should not pass beyond the line 32. 45 It is preferable to placeinformation adjacent the back of the calendar to advise one as to itsmode of operation.

Having thus described my invention, it is obvious that variousimmaterial modifications may be 50 made in the same without departingfrom the spirit of my invention; hence do not Wish to be understood aslimiting myself to the exact form, construction, arrangement andcombination of parts herein shown and described or uses men- 55 tioned.y
